chore: update @actions/artifact to version 2.3.2 and refactor uploadSarifArtifact function

- Updated the @actions/artifact dependency from version 0.5.2 to 2.3.2 in package.json.
- Refactored the uploadSarifArtifact function to use DefaultArtifactClient instead of the deprecated create() method.
- Enhanced the uploadArtifact call to handle the UploadResponse object and log the created artifact's id and size.
